The game by itself is designed to kickstart the royalty progression quite early with an intro quest.
The issue with depending on a scenario to do this is that now the other scenarios are quasi-broken. The solution had to be something that worked with any scenario. And once that's established, the value of a new scenario didn't seem that great. It's not a bad idea at all it just wasn't the best of everything we had to work on. I suspect most people would prefer to get more quests or more psycasts, etc.
